Abstract
Enzymes are immobilized on non-porous glass fibers by coating glass fibers with a solution containing an enzyme and a soluble polymer and contacting the coated fibers with a controlled amount of cross-linking agent to obtain an immobilized enzyme having high activity and long endurance, and which provides a high percentage of conversion. The enzyme may be an amylase, the polymer a plyalkyleneimine and the cross-linking agent glutaraldehyde. Continuous immobilization can be carried out by moving continuous fibers to applicator stations for applying a solution of enzyme and polymer and a solution of cross-linking agent.
